WATER-CLOSET SEAT.

Application filed March 25, 1926. Serial No. 97,195.

An object of the invention is to provide a of Wet magnesium chloride to provide a water closet seat of material which hasa plastic product. This coating is preferably particularly low heat conductivity whereby cast about the core 6 by the use of suitable: it will not seem unduly 001d, molds, it being noted that the composition Another object of the invention is to prodescribed will tightly grip the core as it sets, no vide a water-closet seat which is particularthe surface of the latter being preferably 1y light, durable nd Sanit ry, left rough to facilitate the gripping effect.

The invention possesses other objects and The layer is preferably rendered non-porous features of advantage, some of which, with by filling in the pores and otherwise treating m the foregoing, will be set forth in the follow the surface thereof just before the layer 65 ing description of the preferred form of sets.

It is to be understood here shown anchoredby means of nails or that I do not limit myself to the showing pins 14 driven into the core, with the result 70 made by the said drawings and description, that an additional bond between the core and as I may adopt variations of the preferred layer 12 is insured and reinforcinent against form within the scope of my lnvention as bending of the seat is provided, set forth in the claims.

A cover 27 may be provided in conjuncmarble dust, silica and magnesite in the aption with the seat, and is preferably also proximate proportions of 13201750 connected to the pivot pin 21. The cover parts by dry weight, with a suitable quantity may be formed entirely of wood or, if de- 11 sired, it may be constructed along the general lines of the present seat. Preferably provided adjacent the front edge at its an derneath side are rubber bumpers or rests 26 which are arranged to rest on the upper edge of the toilet bowl (not shown) for the support of the seat thereovcr.

It will now be particularly noted that the seat structure herein-described, While having its outer surfaces of non-metallic substances, is, by reason of the peculiar structure there of, particularly resistant to fracture by bending, and in fact, much stronger against fracture than it would be if molded of a solid mass of the plastic composition. Furthermore, the provision of the non-metallic core is particularly "aluable, since internal stresses due to expansion or contraction are entirely lacking, so that a seat constructed in accordance with the foregoing is particularly durable.

I claim:

1. A Water-closet seat comprising a core member, an inner coating of nonanetallic material fixed thereto and including a fabric layer overlying a portion of said inner coal:- ing, and an outer coating of self-drying enamel fixed on said inner coating.

53. A Water-closet seat comprising a wooden core member, an inner coating of non-metallie composition entirely enclosing said member, metallic reinforcing imbedded in said coating at the lower face of said seat, cloth secured to and overlying said coating at the upper face of said seat, and a continuous outer coating of enamel covering said coat-- ing and cloth.

3. A Water-closet seat comprising a nonexpansile core member, a coating of non metallic composition secured to and enclos lug said core, means reinforcing said coating at the lower face portion of said seat, a fabric secured to and orerhying the upper face portion of said coating, and an outer coating of non-metallic material covering said first coating and said fabric.

4;. A Water-closet scat comprising a uni fury nonanctallie core member, an inner coating of non-metallic con'iposition entirely enclosing said member, metallic reinforce ment imbedded in said coating at the lower face of said seat, and a continumis impervious outer coating covering said inner coat-- ing.

:3. A water-closet scat comprising a nonmetallic core member, an inner coating of non-metallic composition entirely enclosing said member, cloth secured to and overlying said coating at the upper face of said seat, and a hard and impervious outer surfacing for said cloth.

In testimony whereof, I have hereunto set my hand at Oakland, California, this 12th day of March, 1926.
